A very useful Web-based tool called the Global Powder Metallurgy Database now exists to search properties for nearly 2,500 powder metals. The database has been created by parts manufacturers and powder producers across the world through three trade associations: the Metal Powder Industries Federation (MPIF), the European Powder Metallurgy Association (EPMA), and the Japan Powder Metallurgy Association (JPMA). You an find detailed mechanical, physical and fatigue properties for materials identified by ISO or MPIF code. Materials include structural steels, stainless steels, soft magnetic alloys, bearings, and nonferrous. Once you discover grades with acceptable properties, the Web site guides you to specific contacts at suppliers. Data can be downloaded as Excel or FEA software files. Data for metal injection molding was added last year. Use of the database is free, but registration is required.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
